2) an arc subtends an angle of 120 degree at the center of a circle of radius 42cm. Find the length of the arc if pie is 22 over 7.
=========
No math problems with pie, unless it's a pie chart.
Use the Greek letter pi.
And, pi is not 22/7.

3) calculate the area of a sector of a circle which subtends an angle of 45 degree at the center of the circle of radius 14 cm.
1) what angle an arc 22 cm in length subtends at the center of a circle of radius 21 cm?
Central angle = radians.
2) an arc subtends an angle of 120 degree at the center of a circle of radius 42 cm. Find the length of the arc if pie is 22 over 7.
The length of the arc is cm. //Please do not write pie for pi ( ).
3) calculate the area of a sector of a circle which subtends an angle of 45 degree at the center of the circle of radius 14 cm.
The area of the sector =
